struct FTrajectorySample

Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere BlueprintReadWrite float AccumulatedSeconds The relative accumulated time that this sample is associated with Zero value for instantaneous, negative values for the past, and positive values for the future
Public variable UProperty Category, EditAnywhere BlueprintReadWrite FVector LinearVelocity Linear velocity relative to the sampled in-motion object.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite FTransform Transform Position relative to the sampled in-motion object.

Functions
